Further, an elevation driving portion 126 is installed at each of the first and second elevating members 123 and 124 to elevate the first and second elevating members 123 and 124 along the first and second guide roads 121 and 122, and the elevation driving portion 126 is provided with first and second racks 126 a and 126 b respectively installed at front sides of the first and second guide roads 121 and 122, first and second pinions 126 c and 126 d respectively provided at the first and second elevating members 123 and 124 and engaged with the first and second racks 126 a and 126 b, and a pinion driving portion 126 e configured to drive the first and second pinions 126 c and 126 d. The pinion driving portion 126 e may include a hydraulic motor, and driving shafts of the first and second pinions 126 c and 126 d may be connected by a coupling shaft to simultaneously drive the first and second pinions 126 c and 126 d. The elevation driving portion 126 is not limited to the above-described embodiment and may be configured with a hydraulic cylinder, a chain block, or the like.

A first forward/backward movement member 128, which is moved forward and backward by a ninth actuator 127 provided at the first elevating member 123, is installed at the first elevating member 123, and a second forward/backward movement member 130, which is moved forward and backward by a tenth actuator 129 provided at the second elevating member 124, is installed at the second elevating member 124. Rod support members 131 and 132 are installed on upper surfaces of the first and second forward/backward movement members 128 and 130 to support the rod 11.

Further, the rod transfer portion 140 is installed at the first elevating member 123 to transfer the rod 11 supported by the first and second elevating members 123 and 124 to the grasping portion 60 of the rod supply/recovery unit 50 in the horizontal state. The auxiliary rotating portion 150 is installed at the second elevating member 124 to assist the rod 11 to be vertically raised by the rod supply/recovery unit 50.

In the rod transfer portion 140, a push rod 142 having a push plate 141 installed an end portion thereof is slidably installed on the first forward/backward movement member 128, and the push rod 132 is moved forward and backward by a rodless cylinder (not shown) that is installed inside the push rod 132.

Further, a rod guide member 154 having a recess and configured to support the rod is installed at the rod rotating member 151.

An operation of the rod mounting device for a boring machine according to the present invention which is configured as described above will be described below.

As shown in FIGS. 1, 2, and 7, the grasping portion 60 of the rod supply/recovery unit 50 is installed on the body frame 300 to be able to supply the rod 11 to a front side of a boring machine in the horizontal state.

In this state, the pinion driving portion 126 e of the elevation driving portion 126 of the rod supply unit 100 is operated to simultaneously lower the first and second elevating members 123 and 124 installed at the first and second guide roads 121 and 122. In a state in which the first and second elevating members 123 and 124 are positioned below the rod 11 supported by the rod containing portion 110, the ninth actuator 127 and the tenth actuator 129 are manipulated to move each of the first and second forward/backward movement members 128 and 130 forward from the first and second elevating members 123 and 124.

In this state, the first and second elevating members 123 and 124 are lifted by the elevation driving portion 126. In this way, the rod is horizontally laid on the first and second rod support members 131 and 132 installed on the upper surfaces of the first and second elevating members 123 and 124. In this state, the first and second elevating members 123 and 124 are lifted while the first and second forward and backward movement members 128 and 130 are moved backward.

In this state, the rod 11 supported by the first and second elevating members 123 and 124 is lifted to a height equal to that of the grasping portion 60 of the rod supply/recovery unit 50 while maintaining the horizontal state. During the above-described process, the grasping portion 60 is rotated by the sixth actuator 55 so that the rotating member 54 is rotated to direct an inlet to face the front side and the moving jaw 62 is opened with respect to the fixing jaw 61 by the eighth actuator 64.

Further, the rod 11 lifted by the first and second elevating members 123 and 124 in the horizontal state is moved by the push plate 141 installed at the end portion of the push rod 142 as the push rod 142 of the rod transfer portion 140 is moved to the grasping portion 60. Accordingly, a front end portion of the moved rod 11 is inserted into the grasping portion 60.

As described above, when the front end portion of the rod 11 is inserted into the grasping portion 60 by the rod 11 being moved in a horizontal direction, the push rod 142 is moved backward. Further, the moving jaw 62 of the grasping portion 60 is closed by the seventh actuator to grasp the end portion of the rod 11, and, as shown in FIG. 8, the rotating member 54 of the rod supply/recovery unit 50 is rotated by the sixth actuator 55, and thus the rod 11 is rotated to the vertical state. At this point, the auxiliary rotating portion 150 is operated to assist the rotation of the rod 11. That is, the eleventh actuator 153 installed on the second elevating member 124 is operated to rotate the rod rotating member 141, thereby lifting the rod supported by the grasping portion 60.

As described above, when the rod 11 is vertically raised by the rod supply/recovery unit 50 from the horizontal state to the vertical state, as shown in FIG. 9, the base member 52 installed on the support frame 51 is rotated by the driving portion, and thus the rod 11 is inserted through the opening portion 22 to be positioned in the installation space 23.

In this state, the first and second grasping members 33 and 34 of the position setting unit 30 are aligned to be positioned at a line coaxially passing through the driving shaft 311 of the head portion 310 by the fourth and fifth actuators 36 and 37. As described above, when the alignment of the rod 11 is completed, the head portion 310 is lowered, and then the driving shaft 311 of the head portion 310 is screw-coupled with an upper end portion of the vertically raised rod 11 (See, FIG. 10).

When the coupling of the driving shaft 311 of the head portion 310 and the upper end portion of the rod 11 is completed, a grasped state of the lower end portion of the rod 11 is released by the grasping portion 60, and the head portion 310 rises to lift the rod 11. When the rod 11 coupled to the driving shaft 311 is lifted by the head portion 310, the base member 52 of the rod supply/recovery unit 50 is rotated to maintain an initial state thereof, and thus the rod is supplied by the above-described method.

Although not shown in the drawing, the rod 11 supported by the driving shaft 311 of the head portion 310 is supported by the clamp unit to be coupled to a rod that is performing a boring operation. Further, recovery of the rod is reversely performed with respect to the supplying of the rod.

As described above, since the rod mounting device for a boring machine according to the present invention can automatically supply and recover a rod, man-hours of work for supplying and recovering a rod can be significantly reduced and work efficiency of the boring machine can be dramatically improved.
